I did use it to revert from 4.2.1 to 4.1 and it does upgrade the baseband which has isnt what I wanted to do but I didnt read all 55 pages but I can always buy a I-4phone which I've wanted to do,you never know someone or group might come up with a way to sign the firmware but I am sure apple would jump all over that.

Reason: It's called TESTING!!

first i make custom firmware with snowbreeze 2.6 and get my fone in dfu mode and i saw snowbreeze exploiting ireb to my fone....then i shift+restore in itune , after extracting and verifying itunes give error 1600 and says my fone is in recovery mode ..i tried 4-5 times but can't go with it....iphone screen is black and itune is detecting it.....
i tried Ireb/tinyumbrella individually to get the loop or my fone into normal state by hitting exit from recovery or dfu...but nothing worked....and some one help me out what the hell with it.....
power 10 sec
power + home 10sec
release power but home 20 sec dfu mode i used.....
my 6-7 ipsw files are corrupted ...like i download them use it in snowbreeze...and i shift_restore through itunes and give him customfirmware file and it says now the file is corrupted....
and i have used tinyumbrella with tss server on and it results to me same thing....kindly please

I used pwnagetool 4.3.3 for mac today and made a custom 4.3.3 ipsw. It made it, I did the dfu mode, went to itunes, alt-restored with the custom module and it got all the way through but then I got an err 1600. Tinyumbrella 4.3 doesn't see my iphone, so I'm not able to use it to kick out of recovery mode. The only thing that sees it is itunes, but I can't load 4.3.3custom or 4.1custom now.

4. To restore simply press “Start TSS Server” then open itunes, hold down shift(windows) or option(mac) then press restore (tiny umbrella only supports restore not update). A window will open where you can choose the firmware that you want to restore to

Yes. I got that part. Ive read over and over as well.
Ive been trying to say for the past 3 posts,
upon shift clicking in itunes, the window appears, but it doesnt show any of the files that tinyumbrella has saved for me because they are in .shsh but that window that popped up would only show me .ipsw files
